Rotary Blasthole Drills

Rotary Blasthole Drills

In 1952, Bucyrus introduced the first commercially accepted electric rotary blasthole drill, changing mining productivity forever. Bucyrus has continued to improve upon the technology and design to offer the most reliable, productive, and cost-effective means of blasthole drilling. A synergy of robust structures, long-lasting systems, and innovative technology, the Bucyrus line of rotary blasthole drills have proven their effectivenesss and longevity in a variety of mining environments, including both soft and hard rock applications, as well as extreme temperature and high-altitude locations. Equipped to supply rotary blasthole drills of various sizes and configurations, Bucyrus has the drilling tool

that delivers the correct amount of pull-down, rotary torque, and on board air to ensure your

targeted penetration rates.

Bucyrus allows nothing less than the finest workmanship and the best business practices to go into the products we make. Our rotary blasthole drills are no exception. Today, they are one of the most trusted drilling systems in surface mining operations worldwide due to the integrity we build right in.
